1 designates a carton formed from a blank 2 preferably cut from a single piece of suitable carton stock nitecl States Patent Patented June 7, 1960 2 a bottominner side wall 8 adjacent the edge 7 and a bottom outerside wall 9 between the score lines 5 and t5. Score lines 10, 11, 12 and 13 are arranged intermediate the sides of the blank whereby the score lines 3, 4, 6 and 10 define a bottom wall or panel 14 and the portion between the score lines 10. and 11 forms an outer side wall 15. The portion between the score lines 11 and 12 forms an intermediate side wall 16 and the portion between the score lines 12 and 13 forms an inner side, wall 17. A score line 18 is arranged adjacent the side edge 19 to define a top side wall 20 therebetween, the score lines 3, 4, 13, and 18 cooperating todefine a top wall or panel 21. The blank is further provided with slits 22, 23,24 and extending inwardly from end edges 26 and 27 of the blank to the score lines 3 and 4 respectively in alignment with the score lines 6, '10, 13 and 18 respectively to form extensions 28 and 29 on the ends of the walls 8 and 9 and extensions 30, 31 and 32 on the ends of the walls 15, 16 and 17 respectively and extensions 33 on the ends of the top side wall 20. Score lines 34 and 35 are arranged between the score line 3 and edge 26 and the score line 4 and the edge 27 respectively, said score lines 34 and 35 extending entirely across the blank whereby at the ends of the bottom panel 14 there is formed bottom inner end walls 36 and 37 and bottom outer end walls 38 and 39. The

score lines 34 and 35in the portion thereof adjacent the top wall panel 21 provide top inner end walls 42 and 43 and top outer'end walls 44 and 45. I The score lines 3, 4 and 12 are reverse scores relative to the remaining score lines and for convenience of manufacture it is preferred that the score lines 34 and 35 be formed in one operation whereby said scores extend across the extensions 28, 29, 30, 31, 32 and 33. Also, for facilitating proper folding of the carton, it is preferred that the outer side wall 15 and outer end walls 38, 39, 44 and 45 be ofsubstantially the same heighth and that the other sideand end walls be slightly less in heighth.

.;The initial folding of the blank is on the score lines 10, 1 1, 1 2 and 1 3 to-bring the complementary side walls 15 lfiiandzl'lwflat against each other in accordion fashion., Then ,the blank? is folded on thescore line 18 to position the'top side wall 20 at right angles to. the top wall. panel 21 and ;the extensions 33 turned inwardly in edge; engagement with the inner face of the-top wallpanel 21 substantially along the scorelines 3 and 4. The

top end Walls are/then folded on the score lines 3 and 4;;to a position perpendicular; to .thetop wall panel .21;

and the top inner end walls 42 and 43 are turned inwardly on the score lines 34 and 35 over the extensions 33 to form the top section substantially as illustrated in Fig. 7. The bottom side wall '9 is then folded on the score line 6 and the bottom inner side wall 8 is folded inwardly on the score line 5 to lie flat against the inner surface of the bottom outer side wall 9. The extensions 28 and 29 are then turned inwardlyinto substantially edge engagement with the bottom wall panel 14 substantially along the score lines 3 and 4, and the folded such as double-faced corrugated paperboard. The blank ranged adjacent the side edge 7 of the blank to define extensions 30, 31 and 32 are turned inwardly to overlie the bottom wall panel 14 in edge engagement therewith substantially along the score lines 3 and 4. The bottom end walls 38 and 39 are then turned on the score lines 3 and 4 to engage the respective extensions and the bottom inner end walls 36 and 37 are turned inwardly on the score .lines 34 and 35 respectively and over said extensions as illustrated in' Figs. 7 and 8 to cooperate with the extensions to hold the bottom section of the carton in erected condition. If desired, the end walls and extensions may be secured in erected position by suitable fastening devices such as staples and the like. The article to be shipped is then placed in the carton on the bottom wall and the top section folded on the score line 13 to move the side andend walls of said top section interiorly of the side and end Walls of the bottom section. The sections are then secured in closed position by suitable fastening as, for example, applying a strip of tape 46 having an adhesive coating 47 on one face thereof tothe joint between the top and bottom sections as illustrated in Figs. 1, 3 and 4. This provides a carton having triple thicknesses at the sides and quadruple-thickness at the ends, and further provides an additional three thicknesses of the carton stock in the ends adjacent the corners of the carton to form a very strong high-stacking strength carton. If desired, the extensions on the side walls may be doubled to add further-rigidity and stacking strength at the corners of the carton to protect the contents of the carton against damage during shipment and storage. it is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and. shown except insofar as such limitations are included in the claim.
